[Ron Daniel]  Here's one example to consider - a glossary.
Each 'term' is a resource. It has a couple of properties - label
and definition. Many definitions will have multiple paragraphs,
so they need embedded <p> elements. Some labels (and definitions)
may use specialized terminology and therefore need markup such
as subscripts and superscripts.
